Compatible Replacement & Equivalent Models
When the original 330910-00-03-50-02-00 is unavailable or requires a cost-effective alternative, the following models offer functional equivalence. Always verify system compatibility before substitution.
- Bently Nevada 330910-00-05-05-02-00 — Same NSv series, 5 m probe cable variant; verify extension cable pairing.
- Bently Nevada 330905-00-03-50-02-00 — 3300 XL standard voltage variant; requires driver change if substituting.
- Emerson 330910-00-03-50-02-00 — OEM-equivalent (Emerson rebranded post-Baker Hughes acquisition); direct drop-in.
- EPRO PR6423/010-040 — Third-party eddy-current probe; compatible with 3300 XL monitors when paired with matching driver; confirm gap voltage calibration.
- Metrix ST5484E — Alternative eddy-current transducer; suitable for non-API 670 applications with recalibration.
Note: Replacement models must be validated against the installed monitor card (e.g., 3300/16, 3300/20) and the specific gap voltage range configured in the system.
Why Choose the Original Model

Selection Guide
Use the table below to identify the correct 330910 variant for your application:
- Probe Cable Length: -00-03- = 3 m | -00-05- = 5 m | -00-09- = 9 m
- Extension Cable Length: -50- = 5.0 m | -90- = 9.0 m | -05- = 0.5 m
- Voltage Type: -02-00 = NSv (Non-Standard voltage) | -01-00 = Standard voltage
- Tip Diameter: 8 mm standard for 330910 series

Replacement & Compatibility FAQ
Q: Can I use the 330910-00-03-50-02-00 with a standard voltage (non-NSv) 3300 XL monitor?
A: No. NSv probes require NSv-compatible drivers and monitor cards. Mixing standard and NSv components will result in incorrect scale factor and potential false alarms or missed trips.
Q: Is the extension cable included?
A: The 330910-00-03-50-02-00 is a probe-only part number. The matched extension cable (330130 series, 5 m) must be ordered separately to complete the calibrated transducer system.
Q: Can EPRO or Metrix probes replace this unit without recalibration?
A: Third-party probes require gap voltage verification and scale factor confirmation against the installed monitor card. We recommend bench testing before installation in a live protection system.
Q: What is the typical lead time for this part?
A: In-stock units ship within 2 business days. Contact us for current stock status.
Q: Do you provide a warranty?
A: Yes. We offer a 90-day functional warranty on all units. OEM new-in-box units carry the original manufacturer warranty.
